someone please cheer me up :(

so I got my wallet stolen out of my purse today at Albertsons. I was away from the cart for a few seconds trying to read something and that's when it happened and I don't know what to do :( I'm so fking stressed out. What is the most important thing to do right now?! I already reported my only card as stolen but I have literally every thing else in there.. social, license, so much stuff.
